    Celeron D347 does 7,54GHz on Commando and P4 631@7,48GHz

    I got Celeron D347 L649F240 and tried it on my Commando today
    LN2 ofc

    Valid-> http://valid.canardpc.com/show_oc.php?id=483927
    Vcore was 2,03V and temp -190C

    Nice spii1M also: http://ceemic.pri.ee/c2d/celeron347_19.344.JPG

    Some pictures of the rig: http://ceemic.pri.ee/hardware/ln2_8/
    (Don't mind the temp on Fluke, it reads ~15C less than real on this temp area)

    Greetings from Estonia!

    EDIT: today I tried P4 631:

    Nice result...

    higher voltages are not possible cause of the OVP, right?

    Try OVP mod und go for more... maybe more mhz are possible with 2,1-2,15V

    Damn nice result! Sub 20s is really good for Celeron D...
    Reminds me on my nice Celeron D 347 I overclocked. (Singlestage)
    Oldschool rocks, Commando is such a freaking legend.
    Do you want to try LHe to get 8 GHz?

    OVP came at 2,06V. But 2,02-2,03V seemed "sweetspot" (compared to 2,04-2,05V)

    It's pretty hard to get LHe here in Estonia. Even if I could get it, I'm not that rich

    Those are some massive clocks there. But there is a better board for Cedar Mill & Prescott out there, believe me

    Once again, congrats!

    Must be a 965. Tpower bios won't work, DFI is okay, I tried both, but I think Commando or P5B is fastest with the celerons and pentiums.. I'd like to know for sure though, I love those cpus under LN.

    I'd recommend Foxconn BlackOps X48. the board with the best and most powerful PWM i have ever had. 2.35-2.4V stable on Prescotts/Cedar Mills, PWM doesn't even get too hot. Note that you will need to BSEL mod it to properly run 533FSB CPU.

    Regards,

    Just watch out with Commando, the black SMD tantalum caps around the socket are rated for 2V!

    Keep pushing this celeron!

    Well, no need to do that I think ... You can modify it a bit though, and cool that NB with something like the Swiftech copper NB cooler, with a nice 4cm delta fan screaming at 7k rpm

    That should do the job
